Adding AD40xx SPI IP

EVAL-AD400x-FMCZ Overview

The AD4000/AD4001/AD4002/AD4003/AD4020 family of evaluation boards enables quick, simplified evaluation of the AD4000 family of 16-/18-/20-bit, precision successive approximation register (SAR) analog-to-digital converters (ADCs). The AD4000/AD4001/AD4002/AD4003/AD4020 devices are low power, 16-bit/18-bit/20-bit, precision SAR ADCs that offer high performance with throughputs up to 2 MSPS (1.8 MSPS for the AD4020). The evaluation board demonstrates the performance of the AD4000/AD4001/AD4002/AD4003/AD4020 family of ADCs and provides a simplified interface for a variety of system applications.

The EVAL-AD4000FMCZ/EVAL-AD4001FMCZ/EVAL-AD4002FMCZ/EVAL-AD4003FMCZ/EVAL-AD4020FMCZ evaluation boards, accessible from the EVAL-AD400x-FMCZ product page, are ideal for use with a field-programmable gate array (FPGA) mezzanine card (FMC) low pin count (LPC) connector.

The EVAL board uses the SPI interface via the FMC connector to interface to the FPGA/SoC.

Analog Devices provides all the components needed for the "SPI Engine" which are added to the Quartus Library.

The SPI Engine adds to the memory map and interrupt structure:

Periheral	Address Offset	Size (bytes)	Attribute
sys_id	0x1_0000	8	Unique system ID
button_pio	0x1_0020	16	DIP switch input
dipsw_pio	0x1_0030	16	Push button input
led_pio	0x1_0040	16	LED output display
hdmi_dmac_0	0x9_0000	2K	HDMI DMA Controller
axi_hdmi_tx_0	0xA_0000	64K	HDMI Transmit IP
axi_spi_engine_0	0x4_0000	64K	SPI Engine
spi_dmac_0	0x5_0000	2K	SPI DMA Controller

Periheral	Interrupt Number	Attribute
jtag_uart	f2h_irq0/1[0]	JTAG UART
button_pio	f2h_irq0/1[1]	1 push button (either level)
dipsw_pio	f2h_irq0/1[2]	8 DIP switch inputs (falling edge)
hdmi_dmac_0	f2h_irq0/1[4]	Video DMA Controller
spi_dmac_0	f2h_irq0/1[5]	SPI DMA Controller
axi_spi_engine_0	f2h_irq0/1[6]	SPI DMA Controller
